the game is realy realy realy good if you think of it without BUGS i don't mind the bad translate ... but the bugs .. (you come from work exited that one of the game you liked in the past geting english translation ... and then boom bugs ) .... i feel like Cyberpunk feeling here .In theory it should be possible. The versions should use the same image format for RPGMV games.
Don't have the jap version though so no testing from me.
All in all I dont thing the devs did themself a favor for releasing this mess. Presumably they did it by themselfs. It really truly is awefull xD
